Just saw the result. Don't understand why I lost in the component diagram.

Thank you to everybody that contributed to this forum.

Congrats Kate.

Can you provide some detail regarding your preparation :-

1. Did u use petstore for any reference ( I am planning to use the command pattern that is described there). Are there any drawbacks/complications with that design pattern

2. The much debated topic "segment-flight", from what I understood is : a segment is one take-off and landing. So a segment contains ONLY one flight. A flight may be part of multiple segments, but from the customer's point of view, its a one way relationship (from segment to flight) and its legal to consider 1-1 relationship between Segment and flight (Or did u change the BDOM ???)

3. How long did u take to work out the assignment ???

Much appreciated if u can send a reply to this.....

Thanx

1. I did go through PetStore but cannot say I followed the same design. Yes, I used the command pattern.

2. Yes, I updated the multiplicity in the BDOM. My segment could have mutiple flights.

3. I took three weeks to complete the assignment, more hours on the weekends. I would have like to spend more time but rushed through to finish before going on my vacation.

Good luck!

Kate, can you please elaborate (if that doesn't violate the SCEA policy) how a segment can contain multiple flights. Say for eg: if a person goes from A-B via C, Then A-C is one segment(in 1 flight) and C-B is another segment (in another flight). OR did u conside A-B as one segment (which will then make sense to consider multiple flights in 1 segment).

In your sequence diagrams did you show it on class level from your class diagram or did you show it on component level or even just on a conceptional level?

How many classes did you have in your class diagram?

Also, what did u use to access the persistent layer:- CMP with CMR (local interfaces) OR BMP with DAO ???

If a person wants to go from A to B, A-B is one segment and it can contain A-c, C-B or A-D, D-B. If you look at any of the travel sites, the flight you select can be non-stop or with 1 or more stops. That is what I consider a segment. There are many posts on this forum regarding this topic. I used CMP with CMR.

My sequence diagram had more in common with the component diagram. I had 12 classes.

Wow, 12 classes (only)! I am always amazed of people having 30 (or more) classes. But apperantly you can pass with a (relatively) low number of classes, I guess, if you pick the correct classes

Did you have something like a "ShoppingCart" concept?

Yes, though not exactly a shopping cart but something to store session data.

What did you call this "ShoppingCart" in your class diagram? Further did you persist unpaid and paid itineraries or only paid ones? And last, did you use only CMP or did you use DAO/Fast Lane Reader for e.g. searching?

Thanx Kate for your reply ...

Did u use any books while doing the assignment, also can you please list other references you used?

Did u had real experience in architecting using J2EE ? The reason why I am asking this is, I don't have real design and architecture experience, though I have done projects in J2EE and pretty comfortable with the technologies. I am going through petstore, and am trying to understand its architecture and design. Where do u think I should start from (I mean a person with less design and architecture experience), and other books and references I should use ? [ July 20, 2005: Message edited by: Giju George ]
